Claims54
A methods for producing a laminated body wherein the method comprises the following steps:
- providing a first laminating film, with a first surface and a second surface opposite it,
- providing at least one transfer film, which comprises in each case a carrier film and a decorative ply which is detachable from the carrier film and has a first surface opposite the carrier film and a second surface facing the carrier film,
- printing a radiation-curable adhesive on the first surface of the first laminating film and/or the first surface of the decorative ply of the at least one transfer film in such a way that the radiation-curable adhesive is applied to the respective first surface of the first laminating film and/or the decorative ply in one or more first zones and forms a radiation-curable adhesive layer in the one or more first zones, and is not applied to the respective first surface of the first laminating film and/or the respective decorative ply in one or more second zones,
- applying the at least one transfer film to the first surface of the first laminating film in such a way that at least one partial region of the one or more first zones with the radiation-curable adhesive layer and at least one partial region of the one or more second zones, in which the radiation-curable adhesive layer is not applied, are arranged between the first surface of the respective decorative ply and the first surface of the first laminating film,
- at least partially curing the radiation-curable adhesive layer,
- peeling the at least one transfer film off the first laminating film, wherein, in one or more first partial regions which overlap with at least one of the first zones at least in regions the decorative ply is detached from the carrier film when peeled off and remains on the first laminating film, and in one or more second partial regions the decorative ply remains on the carrier film and is peeled off with the carrier film, and
- laminating several successive films comprising the first laminating film with the one or more first partial regions with the decorative ply and at least one second laminating film to form the laminated body.

A laminating inlay
- comprising a first laminating film, with a first surface and a second surface opposite it,
- wherein at least one decorative ply detached from a carrier film of at least one transfer film and a radiation-curable adhesive layer, which is at least partially cured, arranged between the decorative ply and the first surface of the first laminating film are provided in one or more first partial regions, and the at least one decorative ply is not provided, and is peeled off with the carrier film, in one or more second partial regions.
A laminated body
- comprising several successive films with a first laminating film, and at least one second laminating film, which are laminated with each other to form the laminated body,
- wherein the first laminating film has a first surface and a second surface opposite it,
- wherein at least one decorative ply detached from a carrier film of at least one transfer film and a radiation-curable adhesive layer, which is at least partially cured, arranged between the decorative ply and the first surface of the first laminating film are provided in one or more first partial regions, and the at least one decorative ply is not provided, and is peeled off with the carrier film, in one or more second partial regions.
